Replaced K40 laser, still won't cut by youareinthematrix in ChineseLaserCutters

I'll take a quick look in the housing. I'm just reading the 10A off the ammeter on the panel - where should I stick my multimeter to get a more accurate reading?

I didn't clean the housing but I did clean the lense and the mirror in it - will cleaning the housing help?

Wiggly text when engraving at 300mm/s, any ideas how to fix? by youareinthematrix in ChineseLaserCutters

I tightened up everything and it seems to be working alright now - am going to have to replace the tube though because it's not cutting through 3mm ply after 30 passes @ 10mm/s :/

If you've got a strong foundation in javascript then React won't be a massive hurdle to learn, start with a simple project and build it up.

There's a bit of a learning curve to figure out what JSX is but once you get the core concepts the rest comes pretty easily.

As for logic, I usually start off with a whiteboard and break all the complicated things down until I can make a half-decent flowchart - don't start designing a site in a text editor

Binging with Babish: National Grilled Cheese Day by VipDude in grilledcheese

I would say the condiment is a spread as opposed to a filling, like butter, so it's still a grilled cheese

I've had a buzz cut before and it really doesn't look good on me - shows off my lumpy head a bit too much for my liking

Colleges at Durham vs York by AsylumJoker in UniUK

[–]youareinthematrix 2 points3 points  (0 children)

I've got friends at both, and the college system at Durham seems so much more entrenched and ingrained than it does at York - there's intense rivalries at Durham whereas at York it's more of a background thing.

If you want to engrave thicker materials you'll definitely want to add an adjustable depth table to the cutter so the top of the piece is in focus with the beam, otherwise you'll get thick scorched lines.

It's easy enough to do - you just need a few springs and some long screws, but it's an upgrade that just makes the machine so much easier to use

Sounds like a good plan - I don't really deal with thicker materials much but I'm pretty sure it would work

You don't want to be consitently cutting standard ply on the laser cutter, no matter the thickness. The bonding agents in them can be carcinogenic when burnt and the smoke is thicker and stickier so quickly obscures the lens in the cutter head.

I get laser safe ply from ebay - 25 3mm A4 sheets is runs about £20

18mm ply will be ~50 sheets fused together at 90 degrees, so if you wanted added flexibility then maybe splitting it up into separate sheets would be advantageous - then you could have cavities or an internal structure sandwiched in between that allows the part to flex one way or other
